Your painting a Screen in what is a dedicated Theater............which would seem to indicate you want an experience that goes beyond simply watching a movie in a Family Room.
.............yet you want to select a paint you can have the Painters just grab off a shelf. That's not going to do you any justice at all, just get you finished.
Yes, a great many have gone down that road before, it's always tempting to just do it and be done....but we see so many come back with complaints and sour grape-like exclamations that a request like yours amounts to Fingernails on a Chalk Board!.
It's like this. You can get a Paint that will compliment your Room and Projector, and deliver results beyond your expectations. Or you can just tell them to get a basic acrylic "Interior Water Based
) Enamel" in a White Matte, and you'll get exactly what you paid for.....a "decent" Matte White surface that will give you a sharp image, but can do nothing to enhance your Colors or provide substantially deeper Black Levels.
It's important to know your Projector's capabilities.
The Epson 5040 does NOT
deliver "Theater Quality" Blacks on a Matte White surface. The Blacks it does produce are acceptable to those who don't know anything else by which to judge, but really pretty poor if one actually can make a comparison between such Blacks as seen on a basic White and those seen on surface that has a Contrast Enhancing mix.
I like Epsons for their bright, crisp images, I've used them several times...but I also know and realize that something ALWAYS
needs to be done to enhance their Blacks / Contrast. You see...it is their very brightness that works against the ability for them to produce deep blacks. A fully light controlled, non-reflective room is certainly a necessity that allows a 5040 to do it's best. But it's best is not something to be construed as being "the best" .
A dedicated Theater that is going to be dependent upon a Painted Wall for a Screen should not be something you simply rush out and use whatever is convenient. You simply cannot achieve the vibrant Colors, bright Whites, and deep Blacks that make a Theater experience be what it should be by using a basic White or Light Grey Paint.
If your short of time...don't waste any more time by trying to convince yourself of something you don't know much of anything about. Harsh? Nope...just a plea for understanding and acceptance that the advice you get on here is both informed and proven.
Read and absorb:
- You can use this Dunn Edwards ( Wisp of Smoke DE6344 ) as it is a Cool Neutral color. It should be mixed into the aforementioned Acrylic Interior WB Enamel Flat or Matte.
- The above paint...as is...is a light enough shade of Grey to prevent Whites from looking dulled, but Grey enough to at least enhance Blacks and Color depth a bit.
- If you projected image is within 120" diagonal or less, and the Throw of the 5040 is optimized (...within 10% of the minimum throw required for that size...) your OK.
- Make absolutely certain the Wall is smooth and free of defects (...bumps, ridges, scratches...) because a contrast enhancing Grey will highlight those blemishes.
The above at least grants your wish to consider the use of a DE
paint. A smooth wall that is primed White (absolutely a requirement) and the WOS
sprayed will be better than any Neutral White could possibly be.
Give yourself a couple extra days to assemble some needed additional components to add to the DE-WOS
and you can achieve imagery akin to my posted examples. You do have those couple extra days since this is a Long Weekend. You could have a "special Paint" in your hands by/before next Wednesday. If I could know where you reside I could direct you to the local sources...and if not, it would have been worth the attempt in the least.
Please understand that all this is not an attempt to bend you to someone's will, but rather an attempt to see you achieve something special....that is what we want for every member...not just "Get by-s" and Make do-s". Certainly none of us advocate that you spend more than necessary.....but just the same it is a mandate that we suggest a course that will deliver exceptional results.
